IMPROVEMENT IN PESSARIES.

Specification forming part of Letters Patent No. 222, 1 71, dated December 9, 1879; application filed April 27, 1878.

- To all whom it may concern:

Be it known that 1, DAVID DILLER, of York Sulphur Springs,in the county of Adams and State of Pennsylvania, have invented certain new and useful Improvements in Pessaries; and I do herebydeclare that the following is a full, clear, and exact description of the invention, which will enable persons skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters marked thereon, which form a part of this specification.

This invention relates to ail-improved uterine support or pessary; and it has for its object to obviate the tendency of the supporting-annulus to be thrown out of position in the vagina when the wearer changes positlon, and todo away with the necessity of a tight belt to secure the instrument in place,

which would impede the circulationan objectionable feature when a patient is suffering I from prolapsus uteri and consequent uterine con gestion I To this end the invention consists of a pessary composed of a single piece of spring 1netal, having at one end a screw-thread carrying an adjustable annulus for the uterus,

I and at its abdominal portion aseries of holes, by means of which it may be adjusted to the belt by a set-screw, and at its other end two spring-arms furnished with pads to bear against the abdomen, as more fully hereinafter specified.

In the drawings, Figure 1 represents a perspective View of my improved uterine-supporter, and Fig. 2 a view of the spring'stem and adjustable stem-attachment.

The letters a c c indicate-a series of vertical supports extending upwardly from per- I forated cup 0, said supports carrying a flaring annulus, b, at their upper ends.

The bottom of the cup 6 is provided with i a' central female-screw-threaded opening, through which passes the vertical screwforming guides, by means of which the parts of the device are-kept in position during their adjustment, which is effected by turning the cup in the proper direction upon the threaded portion f of the pessary-stem.

The abdominal portion of the pessary-stem is provided with a series of apertures, g, through which is adapted to pass a set-screw and nut, h, by means of which said stem may be adjusted to the belt and brought to bear properly upon the abdomen of the wearer.

The upper end of the abdominal portion of a the pessary-stem is made in the form of a bifurcated or semicircular spring, a a, provided at the extremities with pads 19, which bear against the abdomen.

The principal advantage of my improved instrument is its adaptability to the treatment of both prolapsus and ulceration of the neck of the uterusat one and the same time.

In ulceration of the uterus there is almost invariably a slight, if not complete, prolapsus, occasioned by the concomitant congestion and consequent increased weight of the uterus. It would be in udieious, evidently, to introduce an instrument and bring it in contact with an abraded and ulcerated surface-such as the neck of the uterusand so subject the ulcerated part to compression, which would irritate it more and more.

By the improved pessary, constructed as described, the supportingannulus is held properly in place in the vagina, whatever may be the position of the patient, and all liability of the annulus to bear against the ulcerated parts is obviated after the pessaryhas once been properly adjusted to the patient.

I claim- In a pessary, the annulus 1), its supports 0 c c, and perforated screw-threaded cup, all formed of a single piece of metal, combined with the solid spring-metal stem, screw-threaded at one end for carrying a disk, 01, and provided with an opening, an, a series of holes for adjust ing to the belt, and with two bifurcations car rying pads to bear against the abdomen, substantially as and for the purpose set forth.
